Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon slices, in particular to a large-capacity single crystal silicon slice provided with a connecting block. Background Art

[0002] Monocrystalline silicon wafers are a type of high-purity silicon material grown from a single crystal. They are one of the most important materials in the semiconductor industry and are often used in the field of solar cells. They can convert solar energy into electrical energy with higher conversion efficiency and stability.

[0003] Publication number CN212907755U discloses a single-crystal silicon wafer for improving light energy utilization efficiency, comprising a single-crystal silicon wafer body, a double-layer silicon nitride anti-reflection layer, an etched velvet structure layer, an anti-corrosion structure, and an N-type single-crystal silicon wafer. The anti-corrosion structure is provided on the outer wall of the single-crystal silicon wafer body. This not only improves light energy utilization efficiency, reduces silicon wafer corrosion, and extends the service life of the silicon wafer, but also improves the convenience of connecting multiple groups of single-crystal silicon wafer bodies. In existing technologies, when single-crystal silicon wafers are used as materials for making solar panels, the most common connection method is direct welding. While welding can ensure the mechanical strength and connection quality of the solar panels, it brings inconvenience to the disassembly work of the staff when maintenance or replacement is required at a later stage. Therefore, it is necessary to propose a large-capacity single-crystal silicon wafer with a connecting block. Utility Model Content
